Hello to all of you cast bullet shooters and re-loaders of all kinds,
By making a trade with another cast bullet forum member, who frequents the pages of the forum, I now have a Ruger NO.1 in .300 Winchester Magnum. I started to load some 170 gr powder coated and gas checked bullets and some 170 grain jacketed bullets. Before much was done, i discovered that the rifle has too much head space and was going to call Ruger tomorrow and see If there was a possibility of shipping it to them. Then I got to measuring the belts in length and diameter and found there was a lot of differences between the different brands of cases. I have never owned or loaded for any type of belted magnum rifle and while my shop was open, I never had a belted mag rifle come in for work. I got on some of the other shooting and loading sites and picked up a little information, however the cast bullet forum is the only site that I trust with such. Most of the information that I received from our forum is USUALLY CORRECT.
Some people say the case should head space only on the belt, if so the head space is going to vary from case to case. Others say to head space on the shoulder. With the new cases that I bought the rifle certainly has too much headspace if using the belt to measure headspace. Other brands of cases check out fine when checking headspace from the belt.
I'm not going to ask any specific questions, because I feel I will get more feedback if I just let readers chip in any information dealing with different aspects of loading the .300 Win. Mag and along with their rifles and the experiences that they have encountered with such animals. I hope this works as well as playing dumb, which usually works pretty good.
